The study focuses on selected characteristics of homeless people, a specific group of social aid beneficiaries. Knowledge of particular characteristics is necessary to choose communication strategies to assist the monitored group of people, as well as to set the appropriate forms of social interventions. Objective data regarding the Czech homeless population are only available in very limited numbers. Under the current conditions there are available data on homeless people’s numbers, sex, age, marital status, education and incomplete data on homeless people’s mortality while other characteristics are missing. With some caution, we can use the data provided by foreign studies. Furthermore, experts who are providers of social services for homeless people have been addressed to assess selected characteristics of homeless population. 92 experts having personal experience with homeless people have been addressed in total.
